Prefabricated wall with ventilation mechanism

ABSTRACT

A prefabricated wall with a ventilation mechanism is provided in the present invention. Generally, it includes a ventilation mechanism that lets air exchange in a room from the wall. People can adjust the inlet airflow with a controller. The ventilation mechanism has several holes on the outer surface which face to outside. The outdoor air can pass through the holes and filter into the inner room, consequently fulfilling the function of the ventilation duct. The room equipped such a prefabricated wall does not rely on an HVAC system to have fresh air exchange.

FIELD OF THE INVENTION

The present invention relates generally to a prefabricated wall and,particularly to with a prefabricated wall with a ventilation mechanism,which has resulted in a flexible adjustment of the volume of the airflowand control on the open and close of the ventilation.

BACKGROUND OF THE INVENTION

With the development of internet and social media, an individual onlinebroadcasting or video conference is increasingly popularized in modernsociety. Not only celebrities or professional actors but also commonpeople throughout all the industries are streaming online. It can bedetermined that broadcasting or video conference online will spread morewidely in the future with the blooming of innovations in communicationand the internet.

Plumbing is one of the most important processes in construction. Itcosts a lot of time and labor but may not be durable for a long time. Inthe plumbing or ventilation process, an HVAC system has been generallyincluded to deal with the problem of ventilation. HVAC stands forHeating, Ventilation, and Air Conditioning. HVAC refers to the differentsystems used for moving air between indoor and outdoor areas, along withheating and cooling both residential and commercial buildings. Therein,Air vents process or system makes the most impact in the house. Aqualified ventilation configuration may keep the house warm and cozy inthe winter and feeling cool and fresh in the summer. In addition, theventilation construction plays an essential role in filtering outdoordust and cleaning indoor air to keep mold free and maintain fresh aircirculating at optimal comfort levels.

Usually, the ventilation mechanism in the art has an opening for theexchange between indoor and outdoor air, optionally combined a filter.Such ventilation mechanism has a significant drawback. For example, dustbuildup will be deposit around the opening over times when the outdoorair flows through the opening, consequently blocking the opening. Inaddition, the general placement of the filter in the ventilation systemwill deteriorate the filtering efficiency.

To obtain fresh air with a good quality, we combine the ventilation withan HVAC system, but it may take up much space height in a room. Onanother hand, it will cost much on electricity usage. Users cannotadjust ventilation volume individually in each room. The problem is thatthe centralized ventilation system will occupy too much space andresources. Fresh air pass through too long before they get to a givenspace. Such design seems neat in construction but has many defects.

Thus, there is an urgent need for facilitating the ventilation andenhancing the efficiency and flexibility thereof.

SUMMARY OF THE INVENTION

In this invention, a prefabricated wall is provided. A ventilationmechanism is combined with a prefabricated wall. The mechanism allowsairflow directly to pass through the wall from outside, and will beeasier to control room by room. Since the mechanism has been pre-set, itwill reduce many costs in the plumbing process.

One of the objectives of the present invention is to solve thefiltration failure and vent clogging of ventilation system in the art.

Another of the objectives of the present invention is to reduce the costof installing the integrated air conditioner system.

This invention can not only be applied to houses but also can be appliedto some buildings. Especially for some skyscrapers, HVAC will take muchplace and waste the floor height. In an HVAC system, the ventilationpipe is relatively thick depending on the estimated human flow rate.This problem is brought about by the centralized ventilation system. Ifeach wall of the building is able to ‘breath’, then the ventilation pipewill not need to be such thick.

At the outset, it should be clearly understood that like referencenumerals are intended to identify the same structural elements,portions, or surfaces consistently throughout the several drawingfigures, as may be further described or explained by the entire writtenspecification of which this detailed description is an integral part.The drawings are intended to be read together with the specification andare to be construed as a portion of the entire “written description” ofthis invention as required by 35 U.S.C. § 112.

As an embodiment of the present invention illustrated in FIG. 1 , aprefabricated wall assembly 100 of several modules is provided. Theprefabricated wall 100 comprises a main body 108, at least oneventilation mechanism 102, and at least one window 104. Generally, themain body looks like regular wall panels with structure inside, overall.Window 104 can be set in a specific module, which is suitable for beinginstalled in the prefabricated wall 100. The main body 108 can beassembled with the top and bottom modules, including other functionalparts, like warm or cool units. Adhesive or screws are not limited, buttightly fixed with different modules to integrate them. The window spaceis reserved for future use. The entire prefabricated wall 100 isdesigned as boxes, and they can be overlayed one by one. Preferably, theventilation mechanism 102 is well positioned at the four corners of theprefabricated wall 100. Each ventilation mechanism has a cover with aslot 106 to cover thereon, letting fresh airflow enter the room from theinterspace. Since the slot 106 is a small invisible design, it will nothave a bad aesthetic effect on the prefabricated wall. When the windowis closed, people are still able to have a nice atmosphere insidedepending on the fresh air from the ventilation mechanism 102. Inextreme temperature periods, the closed window will keep the room at anappropriate temperature and the ventilation mechanism 102 let oxygen andfresh air enter the room.

Such a prefabricated wall with a ventilation function in the embodimentoffers fresh air directly from the wall, preferably from the outside ofroom. When the ventilation process is decomposed into part by part, itwill solve the set-up problem and cost issues. The main body 108 will belike regular walls in the art. Preferably, the prefabricated wall can bedivided into more pieces depending on need such as some layers of“boxes” stacked with each other by some mechanism locks. Thus, it'sflexible and detachable.

In a manufacturing process for the prefabricated wall assembly, the fourcorners of the wall are preset with a ventilation mechanism. Forexample, the four corners may be dented with a pre-measured depth forthe ventilation mechanism, so that the overall appearance of theprefabricated walls is a flat “panel” shape when looking outside.

FIG. 2 a shows another embodiment of the present invention. CombinedFIG. 2 a clearly shows the exploded view of a ventilation mechanism inthe prefabricated wall 200. In the embodiment, the ventilation mechanism25 has a cover 12 to cover itself. Similar, the cover 12 has a slot.When the cover 12 has been removed, it is clear to see internal partsinside the ventilation mechanism 25. This ventilation module realizesthe function of exchanging fresh airflow from outside. As the same withair conduit in an HVAC system, the ventilation module is responsible forkeeping the oxygen concentration in the room. The difference is that theventilation wall is a decentralized process for transporting fresh air.There is no need for getting air from the complicated plumbing systemand energy consuming, but directly from the exterior walls. Eachprefabricated wall 200 face to the outside can exchange air from insideto outside. The constructions of the ventilation mechanism 25 will bediscussed in the below.

FIG. 2 b is the interior of the prefabricated wall 200. The entireprefabricated wall 200 can be divided into parts depending on what kindof module is needed. In this embodiment, the middle part of theprefabricated wall 200 is hollow. Filled in the hollow space are somefilling materials 21, including but not limited into soundproof materialand cool/heat insulation material, to keep the room quiet andcomfortable. The hollow part can be divided into several sectionsdepending on height and transportation requirements. And it also can beinterchanged by a window module as shown in FIG. 1 . The fillingmaterial 21 is also flexible. It can be design as a pyramid shape orother soundproofing design.

In the embodiment shown in FIG. 2 b , the prefabricated wall 200 isformed with multiple hollow boxes. In this example, the main body hasmultiple cubic boxes, but the number of the box is not limited. Theprefabricated wall 200 can be divided into several boxes for moreconvenient transportation. Then the assembly of the wall is built onsome internal lock mechanism, including bolts, screws, pins, etc. Insidethe box, the filling material 21 may be soundproofing sponges and heatinsulation cotton or rubber well-positioned in each box. After thenecessary filling has been set up, the prefabricated wall is coveredwith a panel. The panel can be customized by customers, preferably witha decorative design element. The material of the panel for covering thebox can be either metal, plastic, or wood, depending on therequirements.

The cover on the corner for covering the ventilation mechanism can beeasily removed for replacing the filter or maintenance of theventilation part. The cover is connected with the hollow box in manyways. It can be directly fixed on it with some spikes or adhesivematerial. A hinge can also be applied if there is a convenience need.

Preferably, the top cover 12 is the upper panel for covering theinternal ventilation mechanism 25, and the bottom cover 11 is the lowerpanel which is located at the bottom. The ventilation mechanism 25inside the prefabricated wall used for controlling the airflow inlet tothe room. There is a space 22 inside the prefabricated wall 200 toaccommodate the ventilation mechanism. This space 22 also can be pre-setfor a fan or some other device to help the air exchange process.

FIGS. 3 a and 3 b illustrates the detailed constructions of theventilation mechanism 25 shown in the FIG. 2 a and FIG. 2 b . Theventilation mechanism is covered by the cover, and has an outer surfacefacing to outside with some holes 33, and a board piece 32 with somecorresponding holes 30, whose location overlaps the holes' 33 location.The locations of the holes 33 may be adjusted to control the extent ofthe overlaps between the locations of holes 33 and holes 30. Holes 33are some distributed holes mounted on the outer surface, to let theprefabricated wall 200 be able to get fresh air flow from outside. Thelocation and amount of the holes is not limited. They only need to allowairflow to get inside. Preferably, more than one holes are arranged atintervals in a line. The board piece 32 having the holes 30corresponding to hole 33 mounted on the outer surface. The amounts ofholes 30 and holes 33 are the same. The board piece 32 is movable to beaccommodated to position in different locations. When the holes 30 areoverlapped with the holes 33 exactly, it will result in the maximumvolume of airflow inlet. When moving the board piece 32, the holes' 30locations tend to be mismatched, consequently bringing about at leastpartial block areas, which resulting in a block of air flow fromoutside. The holes 30 will form three ellipses shape and become narrowerand narrower. In the end, board piece's 32 holes 30's locations willtotally move to the bottom of hole 33, consequently without any overlapson the holes 33, in that way wherein the ventilation process is stopped.The ventilation mechanism has a filter 31. To prevent dust and otherharmful substances from entering the room, there is a filter 31 attachedto the board piece 32, which can overlap on the board piece 32. Thefilter 31 is a replaceable filter used to keep particles from enteringthe interior of the prefabricated wall 200. Since the cover 12 isdesigned for maintenance, it will be easier to remove the cover 12 andreplace a new filter 31.

When controlling the ventilation mechanism to adjust the air flow, arack and pinion are integrated into the ventilation mechanism 25. On theright side of the board piece 32, there is a paired gear of rack 34 andpinion 35. Preferably, the pinion 35 is mounted at the side edge of theboard piece 32, and accordingly, the rack 34 is installed with each endof the rack 34 aligned to the pinion 35. The back-and-forth movement ofthe rack 34 cogging on the pinion 35 results in a back-and-forthpressure force to the board piece 32, subsequently leading to a switchbetween match and mismatch of the holes 33 and holes 30. Therefore, anadjustment and control of air flow has been realized.

Visually shown in FIG. 3 b , it has presented a view of the process whenclosing the ventilation, via a movement of the rack 34 on the pinion 35.As introduced above, when ventilation is needed, the holes 33 and holes30 on the board piece 32 will match, forming an air inlet channel thatlet the fresh air come in. Optionally, when a minimum of air flow isneeded, the partial overlap between holes 33 and holes 30 may be set.Alternatively, the paired gear of rack and pinion 34, 35 is not the onlyway to control the movement of the board piece 32. It can also beconnecting rod, shaft or other connecting mechanisms which enable aback-and-forth movement. For example, the ventilation parts can belinked with a belt drive or a connecting rod, alternatively. Such amechanism will be able to control all the mechanisms.

In sum, the rack on the pinion will control the system open and close.The controller is not limited to rack and pinion but also can be ahydraulic rod, etc. And ventilation modules all over the corners wouldalso be controlled together by the same ventilation mechanismstructures.

FIG. 4 illustrates another embodiment in which at least one fan isinstalled in the interior space to help the ventilation process,preferably the fan 41 is installed between the outer surface and thecover. Since the prefabricated wall is modularly fabricated, it iseasier to pre-set fans 41 in the ventilation module. The entireprefabricated wall is constructed as a multi-layer box. The ventilationmodule is also a sealed box. After the cover 12 has been closed, it willclose the air transfer from inside to inside (internal air cycle).Therefore, the running of the fans 41 will form a vacuum conditionwithin the box, which transfers the fresh air from outside, and blowsthem into the room. Adjustment of the spinning speed of the fan willalso control the inlet airflow. Preferably, all the fans and controllerswill be merged into a control board. Input and output are reserved forthe power supply from room wiring.

FIG. 5 shows an exploded view of another embodiment of the presentinvention. The prefabricated wall 500 has multiple different locationsof the air vent. Mainly, the prefabricated wall 500 has a main body 508that is constructed as multiple layers. Optionally, the main body 508has some windows 504 through the wall. In addition, the prefabricatedwall 500 has a cover 512 with some slots 506, and a ventilationmechanism with the constructions with the above embodiments described.In this embodiment shown in the FIG. 5 , preferably, the cover 512 andventilation mechanism are located at the bottom of the main body 508.Furtherly, the prefabricated wall 500 in this embodiment has anair-conditioner system, which is integrated with the ventilationmodules. The air-conditioner system has a set of heating/cooling pipes518. When the airflow inlet from the outside, the heating/cooling pipe518 can adjust the temperature of the airflow. The volume of inletairflow can also be adjusted similarly via the movement of the rack andpinion in the ventilation modules, which controls the entire ventilationsystem.

The invention includes but not limits all the embodiments above.Especially, the parts/modules of the prefabricated wall assembly fordifferent embodiments are interchangeable.

Since many modifications, variations, and changes in detail can be madeto the described preferred embodiments of the invention, it is intendedthat all matters in the foregoing description and shown in theaccompanying drawings be interpreted as illustrative and not in alimiting sense.
